Java Programming for Complete Beginners - Java 16 - Step 10 - List and ArrayList - Sorting - Introduction to Collections

The video tutorial covers creating and sorting lists in Java. It begins with a simple list of numbers, demonstrating how to sort them using the Collections.sort method. The tutorial then progresses to creating a more complex Student class with attributes and methods. Finally, it explains how to sort a list of Student objects by implementing the Comparable interface, highlighting the importance of defining comparison logic for custom objects.

What is the primary reason for using an ArrayList instead of a List created with List.of?

• ArrayList is faster than List.of

• ArrayList allows modifications like sorting

• ArrayList uses less memory

• ArrayList is easier to create

Which method is used to sort a list in Java?

• List.sort

• Array.sort

• Collections.sort

• Sort.list

What is a static method in Java?

• A method that is only accessible within the class

• A method that is always synchronized

• A method that can be called without creating an instance of the class

• A method that cannot be overridden

What is the purpose of the Student class in the tutorial?

• To demonstrate inheritance

• To illustrate the use of abstract classes

• To explain exception handling

• To show how to create a class with attributes and methods

Which Java package should be imported to use the List interface?

• java.io

• java.util

• java.lang

• java.awt

Why is the Comparable interface important for sorting custom objects?

• It allows objects to be compared for equality

• It provides default sorting for all objects

• It defines how objects should be compared for sorting

• It improves the performance of sorting

What must a class implement to be used with Collections.sort?

• Serializable

• Cloneable

• Comparable

• Iterable
